JAMES M. KERR, O NEW YORK, ASSIGNOR 'ro HIMSELF, AND WILLIAM H.

I HUNTER, OF BROOKLYN, N. Y.

BOTTLE-STOPPER.

SPECIFICATION forming part of Letters Patent No. 341,660, dated May 11,1886.

(Yo model.)

To all whom it may concern:

Be it known that 1, JAMES M. KERR, of the city, county, and State of NewYork, have invented a new and Improved Bottle'Stopper,

of which the following is a full, clear, and exact description.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a sectional elevation of my new and improved bottle-stopperapplied to a bottle, the neck of the bottle being broken away. Fig. 2 isan enlarged plan view of the tube with the cork, cap, and valve removed;and Fig. 3 is an enlarged inverted plan view of the cap.

The invention will first be described in con nection with the drawings,and then pointed out in the claims.

The stopper is composed of the tube a, cork I), placed upon the tube,the cap 0, and the ball-valve d, placed in the cap to close the tube a.The upper end of the tube a is made concaved or countersunk to form aseat, 6, so

the ball d will accurately fit the tube and close.

the passage therein air-tight, and so the ball will always rest upon thetube, closing the same when the bottle is upright, and the upper end 0of the tube a is externally screw-threaded to receive the cap 0, whichis'internally screwthreaded at its lower edge. The cap is by preferenceconical in form and formed with a shoulder, f, to retain the cork I),placed upon the tube, and to limit the insertion of the stopper into abottle. The cavity in the cap 0 is somewhat larger than the ball-valved, so

that when the bottle is slanted to either side the ball will uncover thepassage through the tube a, and the cap 0 has the aperture 0', for 0 theescape of liquid from the bottle. To prevent the ball (1 from closingthe aperture 0. when the bottle is turned or inverted, I pass throughthe cap 0 the small wire 0 which always keeps the ball from interferingmaterially 5 with the use of the bottle. In case, however, the bottle issimply tipped upon its side, the conical shape of the cap 0 will causethe ball d still to close the tube a, and prevent almost altogether theescape of liquid.

A stopper constructedin the manner described automatically closesairtight, and at the same time permits the escape of the liquid insuitable quantities by inverting or slanting the bottle. Besides, thestopper is cheap, and in all respects practical.

Having thus fully described my invention,

I claim as new and desire to secure by Letters Patent- 1. As a newarticle of manufacture, a bottlestopper composed of the tube a, cap 0,cork I), placed upon the tube, and the ball-valve (Z, placed in the capto close the tube a, substantially as and for the purposes described.

2. The tube a, countersunk at e, and provided with the cork b, incombination with the apertured cap 0, containing the ball-valve d,screwed upon the tube and provided with the wire 0, substantially as andfor the purposes set forth.

JAMES M. KERR.
